Here's your technological solution: Use more efficient, less polluting (and slower) turbofan engines instead of less efficient, more polluting (and faster) turbojects.
And here's the attendant public policy: Tax the turbojects' users enough to offset the negative ecological externalities incurred by their use. That will likely make commercial SST unprofitable.
- MayeulC 8y agoAs far as I know, and according to Wikipedia, most commercial airliners already use turbofans [1], which are high-bypass turbojets [2]. Unless you were referring to turboprops? [1]: https://en.wikipedia.org/wiki/Turbofan https://en.wikipedia.org/wiki/Turbofan
- jandrese 8y agoAlmost nobody uses turbojets anymore. Certainly not airliners. Even fighter jets use turbofans.
- xenophonf 8y agoExactly my point.
